Serial No. 777,138. i 1

To all whom it may concernv le it known that I, CHARLES L. Heisman,

ot' Schenectady, in the county of Schenecl tady and State of New York,have invented a certain new and uset'ul Improvement in Coal- Passers forLocomotive Tenders, of which improvement the following is aspecilication. l My invention relates to appliances'-v for mechanicallypassing coal from the rear to the forward portion of the coal bin of alocomotive tender, in order to place it within convenient reach of thetireinan for supply as required to the firebox of the locomotive; andits objects are to effect a reduction of weight and cost-in theconstruction of an appliance of such type; to"obviate -tlie necessity'of expensive special modifications of tender construction heretoforeordinarily required for the application of such appliances; and toprovide a--self contained unitary mechanism, adaptable, Without change,for applicationin connection with tender tanks of dierent designs andslope, and which may be applied either singly, or in diiplicatefor coalbins of extra width, and located so as not to obstruct access to thecoal bin, while being at all times readily accessible.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings: Figure 1 is a View, partly in sideelevation and partly j in longitudinal central section, of a locomotivetender, illustrating an application of my inrention; Fig. 2, a verticallongitudinal central section Athrough a coal passer einbodyinginyinvention; Fig. 3,a plan or top view, partly in section on the line a aof .'Fig. 5,; of the same; Fig. 4, a front view,

ilyfinvention,ishereinexempliti'ed as ap` plied in connection 4with alocomotive tender of a present standard form, haying a Wat-er tank, il,of so-called U form, with the usual coal .space or bin, 2, interposedbetween'ts longitudinally extending side portions, at, and tor somedistance. rearwardly from, its front end. The central portion of thetank is forwardly and downwardly inclined at its front end, the platesof which central portion constitute lthe rear wall, 3 of the coal bin.The side walls ofthe fuel' in may also have an inclined or'slopingportion, 3b.

The forward end of the coal bin is controlled by a movable coalconstruction.

In the practice vof my invention,` a fluid pressure operating cylinder,4, .they axis 'of which is inclined at a Correspondingffany le lwiththat of the downwardlyand forwar 1y inclined rear wall of the coal bin,is secured to the top of the tank, adjacent to the rear wall of the coalbin. The cylinder, 4, is fitted with a properly packed piston, 5, secured upon a piston rod, l6, which passes through a stuiting box 4j1, on'the Ifront head of the cylinder. Fluid under pressure', as steam orcompressed air, is'supplied to a gate, 3, ot the ordinary valve chest,7, located on the 'rear` head of COAL-PASSER FOR LOCOMOTIVE-TENDERS. u

the cylinder, to move'the pistonA in ,alter-W nately opposite directionstherein, as from time to time desired, by a distribution valve, 8, ofany suitable and preferred` known construction.

The well knownk Westinghouse.,

air pump valve is one which isI desirably adapted for this service, andis hereinshown as applied.

A reinforcing wear plate, 9, is secured to the rear wall of the coalbinand the adjoin-A ing portion of the floor thereof, which, in theinstance shown, is the top ofthewater bottom or central partof theforward portion of thetank. The lower end of the pis ton rod, 6, issecured toa substantially T shaped cross head. 10, which is fittedtoslide between guides, 11, which overlap llateral flanges, 10, on thecentral portion of the cross head, and aresecured to the wall,.3,

f and rwear plate, 9, by bolm, 11. An articulatedA ramycomprisingaplurality of carrier sections, 12, and one or more vibratable pushersections, 13, is coupled tothe cross head, 10, by atransverse hinge pin,12., and the carrier sections lare coupledone to another by similarhinge pins, 12b, said pins passing through lugs on the cross head andcarrier sections. The pusher sections, 13, which are of substantiallyrectangular form, and may be toothed or serrated on their upper sidesthroughout the whole, or any desired portion, of their length, areprovided with downwardly projecting lugs, 13,

on their lower sides for the reception of the p ins by which they are.coupled tothe carr1er sections. In the instance shown, one

"pusher section is interposed between the' cross head and the adjoiningcarrier section; another between the two carrier sections, and a thirdis located adjacent to thev forward lend of the forward carrier section,to `which it is coupled by a hinge pin, 13b.

The forward and backward traverses of the cross-head, 10, whenactuatedby the piston of the., operating cylinder, are made over the'surface ofthe inclined reinforcing wearl plate, 9, and those of the carriersections and pusher sections over said surface,

the surface of the floor of the coal bin, and the connecting lowercurved surface of the rear wall, 3, the articulation of the sectionspermitting them' to follow the change of direction of said surface. Thetrue rectilineal movement of the sections is insured by a guide, 14,which is secured to the floor of the coal bin and fits in correspondinggrooves in the plate sections. The piston rod is protected from contactwith the fuel in the coal bin by a segmental shield, 15, extending fromthe operating cylinder to the line of the upper end of the cross headwhen the latter is at the forward extremity of its traverse.

The pusher sections, 13, are pivoted freely on their hinge pins, and areswung downwardly thereon, in the rearward traverses of the piston, bythe pressure of the coal above' them, into the positions shown in dottedlines in Fig. if.' They are correspondingly swung upwardly, into thepositions shown in full lines, by the pressure of the coal, in theforward traverses of the piston. If desired, rollers, 16, may be mountedon the `hinge pin, 12b tolassist in supporting the carrier sections anddiminishing the fricvtional resistance to its movement.

In the operation of the appliance, the coal is moved forwardly in thecoal bin by the action thereort of the pusher sections, 13, during the`downward transverses of the pist-on, and thereby placed wit-hin reachof the firemans shovel, when working on thefollow and conform totheplanes of the ioor and rear walls of the coal bin, and, for

its application and operation, involving no changerwhatever in the formor relation of the boundaries of thecoal bin over which it traverses.The practical structural and operative advantage of this feature will beobvious to those familiar with railroad service.

If the slope of the rear wall, 3, is not suiliciently steep to readilygravitate the fuel to the bottom of the bin, supplemental pushers, 21,pivotally mounted on swinging arms, 22, and operated by coupling rods,23, conf nected to thevcross head, 10, may vbe provided, as illustratedinFig. 7 of the drawings A n, v

When the sloping sections, 3b, of the side walls are omitted, or whenusing a single coal passer in a wide bin, additional means may beemployed for assisting the movement of the fuel from the sides towardthe middle of the bin. As shown in Figs. 7 to l2, such additionalA meanscomprises a transverse rocking shaft, 17, mounted in bearings, j19, inthe opposite side walls of the fuel bin, a short distance above thebottom, the shaft being further supported by additional bearingbrackets, 19a, if desired, and carrying a plurality of downwardlyprojecting pusher sections,` 20, which are mounted to swing uponvertical hinge pins, 20, supported in arms, 20', fixed upon the shaft.For the purpose of imparting a rocking motion to the shaft, the same isprovided with a rigid arm, 18, at it-s 'middle portion projectingdownward, and coupled with one of the reciprocating carrier sections,1Q. As the shaft is thus oscillated to and fro, the pusher sections, 20,swing through a limited angle about their vertical pivots, as determinedby the stop lugs, 20c, always presenting an outward impelling face tothe fuel upon'the forward movement, and thereby moving the fuel awayfrom the side walls and toward the carrier sections of the passer at theAmiddle of the bin. Y j

It will, of course, be understoodthat two or more of the ,coal passerunits may be employed in wide fuel bins, iif preferre d.
